    I am trying to connect to a db instance, but my password has the following special characters: backslash, plus, dot, asterisk/star and at symbol. For example, 12@34\56.78*90 (regex nightmare lol)

    How do I safe pass it to the connection string? My code looks like that:

    connection_string = f'user={user} password={pass} host={host} dbname={dbname} port={port}'

    connection = psg2.connect(connection_string)


    It gives me wrong pass/username error. However, I tried this combination directly on the db and it works, and I tried another combination on the python code and it worked as well. So looks like the problem is the password being passed weirdly to the connection.

    I tried urllib scape, I tried double quotes on the password, nothing works so far :(
